On May 24, 20022, the Washington Post carried front-page news that a court in Ukraine had sentenced a 21-year-old Russian soldier, Vadim Shishimarin, to life imprisonment for the war crime of premeditated murder of a civilian, 62-year-old Oleksandr Shelipov. The session was the first war crimes trial in Ukraine since Russia's invasion three months earlier.
